TO ALL WHOM IT MAY GQNICERN: I

Be it known that 1, WILLIAM P. PORTER, of Pittsburg in the county of Allegheny, and State of Pennsylvania, have invented a new. and useful Improvement in -Rolling Iron and other metals; and I do hereby declare that the following is a full, clear, and enact description thereofl which will enable otliersskilled in the art to makeand use the same, reference bein'g had to the accompanying drawings, forming part of this specification.

Figure 1 represents a cross-section of my improved rolls for rolling axles or other articles longitudinally, taken. in the'line a: :v, fig. 2.-

Fi g'ure 2 represents a front view.

' Figure 3 represents an end View, showing the gear-connections of the'rolls.

Figure '4 is a partial sideiriew of the rolls, showing the position of an axle when rolled.

Similar-letters of reference indicate corresponding parts. I I

This invention relates to an improvement in rolling iron and other metals in the form of railroad axles and other metal bars, and consists in \the. combination ofa vertically-adjustable and a horizontally-adjustable roll,

and a roll baring fixed bearings, arranged in relation to one another and to the frame in such a manner that the iron to be rolled may be dropped between the upper and side roll, and, after the rolling has been completed,

discharged between the side and bottom roll, as will be hereinafter more fully described.

Three rolls, A B C, are geared together to'run in one direction, and B being hung in such manner that they can be moved further from or nearer to the roll G by means ofscrewsa'b. The rolls are all of the some size'and pattern, according to the article tobe rolled between them, the projections and depressions on their surfaces corresponding to the difl'erent shapes and diameters required forrailroad-axles or other metal bars, as shown in figs. 2 and 4.

When an axle or other article is to be rolled, a round bar is first forged or rolled a trifle larger than the size required for the finished article. The roll A is raised to'admit the round bar when hot betiveen the rolls lengthwise. By the revolution of the rolls in ono.direct ioh,-aud continued pressure upon the bar while hot by means/of the adjustable rolls A B,- the bar takes the shape corresponding with the shape of the rolls, and is thus finished by rolling. The roll B is withdrawn, and the axlo or other article drops out. Iron or steel railroad axles or other metal bars, of irregular forms and varying diameters, may thus be rolled as desired.

Having thus described my invention, what I claim as new, ahd'fdesire to secure by Letters Patent, is-.- I

The combination of the adjustable rolls A and B and the roll 0, constructed-and arranged in relation to one another, and to theframe which supports them, as and for the purpose herein described.
